YandexVideoParser
Yandex operates YandexVideoParser, which indexes videos for display in Yandex video search. Its robots.txt token is YandexVideoParser; Yandex says general robots.txt rules do not apply to it, unlike YandexVideo, so compliance is partial. Site owners verify it by reverse DNS to a yandex.ru, yandex.net or yandex.com host with forward DNS confirmation, or with the Yandex Webmaster IP check tool.
Mozilla/5.0 (compatible; YandexVideoParser/1.0; +http://yandex.com/bots)What YandexVideoParser does
The user-agent string is Mozilla/5.0 (compatible; YandexVideoParser/1.0; +http://yandex.com/bots). The visits Yandex describes are for indexing videos so they can appear in Yandex video search, which is the only purpose the check-robots page gives for this token. That page is the single source Yandex lists for the robot, so a site owner works from the user-agent string and the stated purpose when sorting this traffic in logs.
Allowing YandexVideoParser lets your videos appear in Yandex video search. Blocking it removes them from that index. Yandex says general robots.txt rules do not apply to this robot, which it contrasts with YandexVideo, where general rules do apply. A site that wants to control this robot should address the YandexVideoParser token directly in its own User-agent section rather than rely on a wildcard section, since the two Yandex video tokens behave differently on the same file.
To verify a request claiming to be YandexVideoParser, run a reverse DNS lookup on the IP and confirm the host name ends in yandex.ru, yandex.net or yandex.com, then run a forward DNS lookup on that host name and confirm it returns the same IP. Yandex also has an IP address check tool inside Yandex Webmaster. Yandex publishes no IP range file for this robot.
Operator note. It does not take into account the general rules in robots.txt, unlike YandexVideo, which does.
Controlling YandexVideoParser with robots.txt
Use the token YandexVideoParser in robots.txt. Yandex documents limits on how this bot applies robots.txt; see the operator note.
User-agent: YandexVideoParser
Disallow: /User-agent: YandexVideoParser
Allow: /Verifying a request is really YandexVideoParser
Anyone can put YandexVideoParser in a User-Agent header. Reverse DNS lookup on the requesting IP must return a host ending in yandex.ru, yandex.net or yandex.com, and a forward DNS lookup of that host must return the same IP. Yandex Webmaster also provides an IP address check tool.
host <request-ip>
# expect a hostname ending in yandex.ru, yandex.net, yandex.com
host <that-hostname>
# expect it to resolve back to <request-ip>Common questions
Should I block YandexVideoParser?
Block it if you do not want videos from your site in Yandex video search; that is the only effect Yandex documents. Because general robots.txt rules do not apply to this robot, address the YandexVideoParser token by name in robots.txt rather than relying on a wildcard section.
Does YandexVideoParser obey robots.txt?
Partially. Yandex lists YandexVideoParser as a robots.txt token but says general robots.txt rules do not apply to the robot, unlike YandexVideo, which does follow them. Yandex documents this on its check-robots page, which is the only source it gives for the robot.
How do I verify YandexVideoParser?
Reverse-resolve the requesting IP and check that the host name ends in yandex.ru, yandex.net or yandex.com. Then forward-resolve that host name and confirm it returns the original IP. Yandex also provides an IP address check tool in Yandex Webmaster. Yandex publishes no IP range file.

This registry documents how operators describe their own bots so site owners can identify and control them. It does not publish third-party IP lists or guess at undocumented behaviour. To see how your own site responds to automated visitors, the bot detection scanner reads a URL's live response and names the protection it finds.
